Hello @hequn8128! Thank you for your review and comments.
About PR template - I did changes based on proposed #5811. Please let me
know if it is acceptable or not.
About `rowToString` agree. I think it makes sense and I added such tests.
However I faced with some strange behavior (I do not know if it is bug or
whatever else). Commented on the code about that. ---
